One for all you IT bods, I'm looking for a wireless router to get my home set up, but dunno what one to get! there are sooo many

Basically its main use will be to hook my PS3 up to the internet to play games and such, hopefully a router where I can also just plug my PC downstairs so I dont have to mess around making that wireless.

So what what would you lot recommend what, how much did it cost, and where can I get one from?
